Even the Berlin Wall had escapes. We don't need to go that far.

My point exactly. Strangely somehow you disagree.

It's not clear why you insist that a wall must be 100% effective to be of value.

The Secret Service hasn't been 100% effective in protecting the President (Kennedy) - does that mean that the Secret Service protection is useless and should be disbanded?

I see the critical point sailed over your head yet again. Namely, the wall does not have to be airtight - it would be one component of a larger enforcement.

Using your logic, we shouldn't bother with prisons, because convicts escape occasionally.
